Fig. 20, 93W7283, Oviduct, H&E
A cross section through the oviduct is shown here. Many mucosal
folds project into the lumen (L), and the complicated nature of the
folds is evident by the variety of profiles that is seen. In addition to
the mucosa (Muc), the remainder of the wall consists of a
muscularis and connective tissue. The muscularis consists of
smooth muscle that forms a relatively thick layer of circular fibers
(C) and a thinner outer layer of longitudinal fibers (OL).
